Description

Technical Field

[0001] This utility model relates to the technical field of off-road vehicle parts, and more specifically, to a rubber-coated structure for an independent suspension limiter of a special off-road vehicle. Background Technology

[0002] In existing technologies, independent suspension systems for special off-road vehicles are typically equipped with limiters to restrict the suspension's range of motion and prevent damage caused by excessive compression or rebound. However, existing limiters are mainly made of pure metal or pure rubber.

[0003] When the suspension is made of pure metal, a hard impact occurs when the suspension comes into contact with the limiter. This impact not only generates significant noise, affecting the vehicle's comfort and concealment, but also easily causes wear or deformation of suspension components, and may even lead to structural failure. This problem is particularly pronounced in high-frequency impact environments on complex terrain.

[0004] On the other hand, although limiters made of pure rubber have a certain elastic buffering effect and can absorb impact energy to some extent, the low mechanical strength of rubber materials makes them prone to excessive deformation, tearing, or fatigue damage when subjected to high impact loads from the suspension. This can lead to premature failure of the limiter, making it unable to reliably perform its limiting function for a long time and affecting the overall durability and off-road performance of the vehicle.

[0005] These shortcomings limit the effectiveness of existing limiters in special off-road vehicles, and improvements are urgently needed to meet higher strength and cushioning requirements. Utility Model Content

[0006] The purpose of this invention is to design a metal-material rubber-coated limiter that ensures both the strength of the limiter and its buffering and vibration-damping function, thereby protecting the suspension from damage.

[0007] The technical solution of this utility model is: a rubber-coated structure for an independent suspension limiter of a special off-road vehicle is provided. The limiter is fixedly installed at the corresponding position of the independent suspension assembly to limit and control the movement of the independent suspension assembly. The rubber-coated structure for the limiter includes: a connecting plate, a support body and rubber.

[0008] The connecting plate has a disc-shaped structure with protruding ear-shaped small discs at the diagonal positions of the main disc. Each small disc has a through hole. Multiple inverted conical through holes are opened in the central area of ​​the main disc. That is, the opening diameter is larger on the bottom surface of the connecting plate and smaller on the top surface. The support body is an irregular truncated cone shape with a smaller bottom diameter and a larger top diameter. There is a distance between the bottom of the support body and the connecting plate. Multiple annular grooves are provided on the side of the support body. The rubber is a truncated cone shape that runs through the top and bottom. Its bottom fills the through hole of the connecting plate and is fixed to it. The inner side of the rubber covers the side of the support body and is embedded in the groove.

[0009] In any of the above technical solutions, the through hole opened on the small disc of the connecting plate connects to the independent suspension assembly, and the top of the support body connects to the independent suspension assembly.

[0010] In any of the above technical solutions, the connecting plate and the support body are made of metal, and the rubber is made of 9A-HG6-669 rubber material.

[0011] The beneficial effects of this utility model are:

[0012] The technical solution of this utility model adopts a composite structure of metal and rubber, which retains the strength advantages of metal limiters, avoids the premature damage of pure rubber limiters under high impact, and eliminates the hard impact problem of pure metal limiters through the rubber buffer layer, significantly reducing noise and protecting the suspension from damage. At the same time, this design has a simple structure, low manufacturing cost, and is easy to mass-produce. It is suitable for independent suspension systems of various special off-road vehicles, improving the overall reliability and off-road performance of the vehicle. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0019] In the following description, many specific details are set forth in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] This embodiment provides a rubber-coated structure for an independent suspension limiter in a special off-road vehicle. This limiter, as a key limiting component in the independent suspension system, is used to effectively restrict the movement of the independent suspension assembly.

[0021] Specifically, such as Figure 3 As shown, the limiter 20 is fixedly installed at the corresponding position of the independent suspension assembly 10 to limit the movement of the independent suspension assembly 10. When the independent suspension assembly 10 is compressed or rebounded significantly due to terrain bumps during off-road driving, it contacts the limiter 20. The limiter 20 restricts further movement of the suspension through its buffer structure, thereby preventing damage caused by excessive suspension movement and ensuring vehicle stability and durability.

[0022] like Figure 1 and Figure 2 As shown, the rubber-coated structure of the limiter includes: a connecting plate 1, a support body 2, and rubber 3.

[0023] The connecting plate 1 and the support body 2 are made of metal to ensure the overall mechanical strength of the limiter; the rubber 3 is combined with the metal parts through a hot-pressing adhesive process to form an integrated structure and provide necessary elastic cushioning.

[0024] The specific structure is described as follows:

[0025] Connecting Plate 1: This component serves as the mounting base for the limiter. Its main body is a disc-shaped structure, with a diameter designed according to the suspension assembly dimensions. Two protruding ear-shaped small discs are located diagonally opposite the main disc. Each small disc has a through hole for securing it to the independent suspension assembly with bolts or other fasteners, ensuring the limiter is stably mounted on the suspension frame. Furthermore, multiple through holes for filling and securing rubber are located in the central area of ​​the main disc. These through holes have an inverted conical design, with a larger opening diameter on the bottom surface of the connecting plate (facing support 2) and a smaller opening diameter on the top surface (facing away from support 2). This opening structure effectively locks in the injected and shaped rubber, preventing it from falling off or shifting under stress. Simultaneously, the surface of the connecting plate can be treated with anti-corrosion measures, such as galvanizing or spraying, to enhance weather resistance and service life.

[0026] Support 2: This component is the core support structure of the limiter. It has an irregular truncated cone shape (i.e., an irregular frustum shape on the sides), with a smaller bottom diameter and a larger top diameter. The specific dimensions are determined according to the suspension travel requirements. A certain distance is maintained between the bottom of support 2 and connecting plate 1 to ensure that support 2 does not contact connecting plate 1 when subjected to suspension compression. Support 2 has multiple grooves on its sides, arranged in a ring, to enhance the fit with the rubber and improve the bonding strength. This structural design ensures that the support provides sufficient rigid support when subjected to suspension impacts, while optimizing stress distribution. The top of support 2 connects to the independent suspension assembly 10. The pressure borne by support 2 and connecting plate 1 from the independent suspension assembly 10 is transmitted to the rubber 3 connecting them for cushioning.

[0027] Rubber 3: This component serves as the buffer layer for the limiter 20. It is made of 9A-HG6-669 rubber material (or similar high-elasticity, fatigue-resistant rubber), injected through a special mold and hot-pressed to form a tight bond with the connecting plate and the support body. Rubber 3 is roughly shaped like a truncated cone, with its bottom filled and fixed to the through-hole of the main disc of the connecting plate. The inner side of rubber 3 covers the side of the support body 2 and is embedded in the recessed area.

[0028] The manufacturing process of this limiter is as follows: First, based on the functional requirements of the independent suspension in this project (such as travel limit, load bearing, etc.), the relevant dimensional parameters of the limiter are determined. Then, the metal connecting plate and support body are processed according to the design dimensions. Rubber material is injected using a special mold, and the rubber is bonded to the metal parts through a hot-pressing adhesive process to form the final product.

[0029] The limiter provided by this utility model includes both a metal part and a rubber part. When the suspension comes into contact with the limiter, the exposed rubber part first absorbs the impact energy, providing a buffering and vibration reduction effect. At the same time, the internal metal support structure ensures the overall strength and avoids noise and damage caused by hard collisions, thereby protecting the suspension.

[0030] In summary, this utility model proposes a rubber-coated structure for an independent suspension limiter of a special off-road vehicle, comprising: a connecting plate 1, a support body 2, and rubber 3.

[0031] The connecting plate 1 has a disc-shaped structure with protruding ear-shaped small discs at the diagonal positions of the main disc. Each small disc has a through hole, and multiple inverted conical through holes are opened in the central area of ​​the main disc. That is, the opening diameter is larger on the bottom surface of the connecting plate and smaller on the top surface. The support body 2 is an irregular truncated cone shape with a smaller bottom diameter and a larger top diameter. There is a distance between the bottom of the support body 2 and the connecting plate 1. Multiple annularly distributed grooves are provided on the side of the support body 2. The rubber 3 is a truncated cone shape that runs through the top and bottom. Its bottom fills the through hole of the connecting plate 1 and is fixed to it. The inner side of the rubber 3 covers the side of the support body 2 and is embedded in the groove.

[0032] The units in this utility model device can be merged, divided, or reduced according to actual needs.

[0033] In this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.
